Precisely generate sound waves with High Frequency Tones and test the limits of what you can hear. Did you know that our hearing decays as we grow older? Studies show that as we age, we lose our ability to hear up to half of the upper frequency spectrum. Now, you can test that concept within a clean and easy-to-use interface. High Frequency Tones will allow you to generate any frequency up to 20,000 Hz – widely considered the upper limit to human hearing. Potential uses include: • Annoy your friends or classmates without tipping off the teacher or other adults. • Use it as a dog whistle or bug deterrent (both of whom have better hearing than humans!). • Ward teenagers away from an area. • Compete with your friends to determine who has the best hearing! Purchase Frequency Premium for just $0.99 to permanently eliminate ads and choose from four different waveforms.
